Yes. If you temporarily are on a low fiber diet, the easiest way to follow that diet is no fruits, no vegetables, no whole grains! meat, fish, chicken and dairy are fine. You may have white rice and white bread. Only exceptions to fruit/veggies is mashed potatoes and non chunky apple sauce. Not a healthy diet in the long run but necessary in the short(4-6weeks) to allow the colon to heal and recover.
